Left ventricle-right atrial communication could be congenital (Gerbode defect) or acquired as a complication of surgery or infective endocarditis and leads to volume overloading of pulmonary circulation. Two types, direct and indirect types are known depending on the involvement of septal tricuspid leaflet. Transcatheter closure of this defect is feasible and appears an attractive alternative to surgical management. Various devices like Amplatzer duct occluder I, II, Muscular ventricular septal defect device etc. have been used to close this defect. We report two patients, a preteen boy with direct left ventricle-right atrial communication as post operative complication and an adult female with indirect communication who underwent transcatheter closure with Cera duct occluder (Lifetech Scientific (Shenzhen), China).
左心室-右心房交通可为先天性(Gerbode缺损),也可为手术或感染性心内膜炎并发症所致的后天性,可导致肺循环容量负荷过重。根据三尖瓣隔叶受累情况,已知有直接型和间接型两种类型。经导管封堵该缺损是可行的,似乎是手术治疗的一个有吸引力的替代方法。已使用各种装置,如Amplatzer I型、II型动脉导管封堵器、肌部室间隔缺损封堵器等,来封堵该缺损。我们报告了两名患者,一名青春期前男孩因术后并发症出现直接型左心室-右心房交通,一名成年女性为间接型交通,他们均使用中国深圳微创医疗科学有限公司生产的Cera动脉导管封堵器进行了经导管封堵。
